A visible light-responsive photocatalytic titanium dioxide fine particle mixture, a dispersion thereof, a production method of a dispersion, a photocatalytic thin film, and a member having a photocatalytic thin film on its surface

摘要

A visible light-responsive photocatalytic titanium dioxide fine particle mixture capable of easily producing a highly transparent photocatalytic thin film which exhibits photocatalytic activity only by visible light (400 to 800 nm), a method for producing the dispersion, a dispersion liquid, a photocatalytic thin film, and a photocatalytic thin film Member. Two types of titanium dioxide fine particles in which a transition metal component (except for the iron family element component) that enhances tin components and visible light responsiveness are solid-dissolved and a second titanium dioxide fine particle in which iron group element components and chromium group element components are solid-dissolved By weight of titanium oxide fine particles having a particle size of not more than 100 nm.
